crawl data from http://seccionamarilla.com.mx

[login to view URL] is a yellow pages directory service. The usability of the website sucks. I want the data to be dig, and stored in a local database. I want a script(s) that fetch all the information and stored so I can re-run the script again and fetch data again. Categories, geoposition (long, lat) names, state, description, images, logo, graphical add. All this data is public information they release to everyone so it should not be complicated to grep. I would prefer the script to be coded in PHP 5 and the database in MySQL, bids offering the script with this technical requirements will be taken more into account, but it's not an exclusive requirement. The script will run in a Linux server, any 3rd party libraries are accepted (zend fraemwork, PEAR, ezComponents, etc...) The goal is the script to fetch all data.
